Abstract: <P>PROBLEM TO BE SOLVED: To faithfully achieve the brightness of an image at low cost while saving installation space.  <P>SOLUTION: On a screen 2 where an image projected by a projector 1 is displayed by being reflected, light from another light source 3 other than the projector 1 is superpimposed.

Consequently, a CG simulation evaluation experiment can be carried out by faithfully representing the brightness to enable examination with nearly real and more precise view environment and visibility. Further, the screen 2 is divided into strips to form a louver, the light source 3 is installed behind the screen 2 to irradiate the screen from behind, and then high-brightness display can be performed while projectors in use are decreased in number, so that lower cost can be expected.  <P>COPYRIGHT: (C)2004,JPO
